Major Progress on the Little Obed Project!

    Since our fast start on the Little Obed Project in October, we've had to work around the weather, but were blessed with some great days in November and December.  All the cedar revetments got installed to both stabilize and rebuild eroding banks.  The undercut and vertical banks were graded back and then seeded with a native mix of perennials and shrubs and matted to prevent erosion.  We'll be back in March to add bare root trees and shrubs.

    Next we installed native rock along the toe of the new banks to prevent future undercutting.  We also used rock to reinforce existing drops along the clay bottom to stabilize that area.  We built a large rock grade structure to raise the stream bed back above the natural gas pipeline and then created a riparian wetland along the stream channel inside the new banks.  Finally, we spent another week removing invasive plants, particularly privet so that the native plants can get reestablished.

    It was exciting to see the new streambed and banks respond to the heavy rains we had in November and early December.  Now we are looking forward to the planting in March.  We'll be putting together a slide show on the project soon, but for now, there are a few shots of the project below.

Salamanders of Cumberland County

Tuesday, March 3, 2015

4:00 p.m. Common Ground (405 W 4th St)

       We love our frog friends, but they’re not the only stars of the amphibian world here on the Plateau.  Salamanders are also wide-spread and show up in a variety of habitats ranging from streams and wetlands to leaf piles in your backyard.  Mark Thurman of the Tennessee Wildlife Resources Agency will present his talk and slide show on the salamanders of our area and their habitats.  While there are some rare one that are only found here, they are all fascinating critters.  Come learn more!

Native Plant Sale Update

    A team led by Brad Fox is working hard to put together our first Native Plant Sale, which we’re going to do at our booth at the Garden Show on April 24-26th.  Right now, we’re working on finding plants to sell, we will be doing some potting in March, and we will be working on publicity.  We’ll also need workers during the sale.  If you would like to help with this, call Brad at 281-755-2431.

    We've got a plant list together for the sale.  We'll be offering Little blue Stem and Switch Grass, both native warm season grasses,  Beauty Berry, Coral Berry, wild Hydrangea, and native Azaleas for shrubs, and Blazing Star, Black Eyed Susan, Butterfly Weed, Cardinal Flower, Columbine, Blue Lobelia, and Dwarf Iris for flowering perennials.  You can also call Brad to pre-order.

WaterFest Team Forming

    While July seems a long way away, WaterFest is a BIG activity and to continue to make it a success requires a lot of planning and coordination.  Matt Matteson is heading up the effort this year and he’s putting together a team of volunteers.  If you’d like to help in any way, give Matt a call at 742-0153.

     November Activities

    Little Obed Restoration Project

         We expect to have this rock structure completed by the end of the first week in November so that soil that was removed in sloping the banks can be returned as fill in raising the stream bottom.  There will be a couple of other much small rock structures built to reduce further erosion in a couple of other areas of the stream.  About another hundred revetments will be installed, along with seeding and matting the newly sloped banks.  This should keep us busy throughout the month of November.  We welcome volunteers at any time.  If you just want to come out and help get the trash out of the stream, we could use the help.  Call Dennis if you’re interested - 484-9033.

    Field Trip to Rugby

    Meet at Common Ground at 8:30 a.m.

        Here’s an opportunity for two short naturalist hikes in Rugby Tennessee led by State Naturalist Lisa Huff.  She will take us on a late morning hike of the Massengale Homeplace Natural Area, the site of the first pioneer settlement.  This is an easy hike into a beautiful forested area.  Afterward, you can brown bag your lunch or eat at the Harrow Road Café in Rugby.  After lunch Lisa will lead us on the trail to the Gentlemen's Swimming Hole, again an easy hike.  The first hike starts at 11 am Eastern if you'd prefer to drive separately.   Please wear sturdy shoes and dress for cool weather, and bring your camera.  Rugby itself is a historic tourist attraction and there are buildings and a museum to tour as well.  For more information on Rugby, check www.historicrugby.org.
